A completely unrealistic plan though, to anyone who has thought about it for half a second.

A mars colony is probably doable. A self-sustaining mars colony? For the length of time it would take a completely devastated Earth to recover? Absolutely impossible, at least with our current technology.

Think about the level of supply chain you'd need to get something like a computer or a solar panel made on Mars. Where do you get plastic? Iron ore? Copper? Pure fantasy.

It would still be cool to have a colony on mars.

I don't know what it would take to be self-sufficient but neither do you. Eventually humans will have to have a sustainable presence off Earth if we don't want our species to go extinct. Why can't somebody give it a try? Maybe we don't quite have the technology for it yet but it doesn't hurt to have a good go at it. Extinction would be a real tragedy because we might be the only hope of intelligent life in the whole universe ever. It's incredible how not a single other species we know of even comes close despite millions of years of evolution.

Mars colony? After just a few generations the racists among us will positively jump with joy.
